IMPROVEMENT lN CATTLE-CAR BRIDGES.

Specification forming part of Letters Patent No. 155,868., dated October 13, 1874; application filed September 19, 1874.

To all whom it may concern:

Be it known that I, ANDREW H. HART, of Winchester, in the county of Clark and State of Kentucky, have invented a new and valuable Improvement in Cattle-Car Bridges; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawings, mal;ing a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawing is a representation of a sectional view of my cattle-car bridge, and Fig. 2 is a cross-sectional view of the same.

This invention has relation to means for transferring cattle from pens into railroadcars, and vice versa; and it consists in combining a sliding gangway with an elevated bridge leading from a cattle-pen, which gangway can be moved up to and from a car-door by means of a lever, as will be hereinafter explained.

In the annexed drawings, A designates a cattle-bridge, which consists of a floor and two vertical sides, and which is mounted on trestles C, so that the floor from that end from which the animals emerge to enter a car is on a level with the floor of the car. I) designates a bridge, consisting of a floor and two vertical sides, which are free to slide inside of one end of the gangway, and which are secured to long sliding beams 11 b, which work in suitable guides beneath the floor of the gangway A, and are connected together by means ofa crossbar, a. The bridge D may be of any desired length, and it should be long enough to reach from the end of the gangway to the side of a car on the track running past it. D designates a lever, which has its fulcrum at e on one end of the crossbar a, and which is loosely attached to a loop, 0, fastened to a beam, C.

It will be seen from the above description that, while the end of the bridge A may be safely out of the way of passing trains, the bridge D can be moved up closely to a car and animals driven into the car without danger to their lives or limbs.

What I claim as new, and desire to secure by Letters Patent, is

In combination with an elevated cattlebridge, A, the sliding bridge D, guided and supported by beams b, and movable by means of the lever D, substantially in the manner and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

ANDREW H. HART.
